PWR Connector
When connected to an installed DR8 board, the PWR connector (Figure G-5)
only utilizes the pins for the multi-function signal (MFSIG) and signal ground
(GND). The power pins are not connected to the board.
Figure G-5: Front Panel PWR Connector
When installing the Driver/Receiver Board, be sure that the correctly marked
PWR cable (inside the module) is connected to its specific board – the cable
marked DRA for the DRA board and marked DRB for the DRB board.
Incorrect installation may cause you to be connected to the wrong MFSIG.
Table G-7 shows the connection names, pins, and descriptions for the PWR
connector.
